  1. If we had a spherical capacitor and the voltage across it is 1000 V, I need to know the charge on every plate, I know 2 ways to solve this either using C=Q/V or V=Q/r * 1/4*pi*Epsilon. So, which one should I use, and why?

  2. Another thing, according to hyperphysics the formula for the capacitance of the spherical capacitor = 4*pi*epsilon / 1/a - 1/b. Does that mean that the dielectric constant of the dielectric has no effect like parallel plates?
